GAS-BURNER.

Specification of Letters Eatent.

latenteel S Application led December 16g 1995, Serial No. s922755. Renewed .uly 25,1912; Serialic. L.

To all whom t may concern.'

Be it known t-hat I, THOMAS B. WYLIE, of Qsborne, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Gas-Burners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a sectional side elevation of my improved burner; Fig. 2 is a cross section on the line II-II of Fig. l; and Figs. 3 and 4: are details.

My invention relates to gas burners, and is designed to provide a more thorough and complete mixture of the air and gas than has heretofore been attained. To that end, the invention consists in introducing the air into the mixer tube in tangential jets, so that a swirling motion is set up in the mixer tube to thoroughly intermingle the entering air with the jet of gas.

In the drawings, 2 represents the gas supply pipe which leads to a casting 3, forming a valve casing. The angle valve casing is provided with a hand-operated valve rod 4, extending to the valve 5, which' parts may be of any desirable form. The portion forming the valve seat is provided with a surrounding flange 6. to which is bolted a sheet iron ring 7.

. To the inner face of this sheet iron ring are secured the sheet metal'blades 8, which are inclined at an angle to the radius and may be held by any suitable connections. For example, I may provide the sheet metal ring with holes into which projections enter at t-he ends of the blades or the ends of the blades may be flanged and riveted to the sheet iron ring. If the burner is small, the blades may be formed by slitting and bending them in from a sheet metal tube. At their other ends, the blades are similarly secured to another sheet metal ring 9, which is secured to the flange l0' of the burner nozzle 11, which may be formed of a casting.

In order to strengthen the mixer tube I also employ long qscrews or bolts 12, which extend through the flange' 10 and through the rings i' and 9, to hold the parts together.

.In order to control the supply of entering air, I preferably employ a tube or 'sleeveV 13, which fits over the mixer tube and may be slid endwise thereon. This may be held any desired position by friction on the mixer tube and may be adjusted to give the desired amount of air supply.

The advantages of my invention result from the angular entrance of the air currents. These entering currents being directed radially, set up a swirling acti-cn withinv the mixer tube, so that the gas is thoroughly mixed with `the air before entering the nozzle.

Many variations may be made in the form and arrangement of the parts and in the size of the burner without departing from my invention.

I claim: y y

l. In a gas burner, a mixer comprising a cylinder constructed of a plurality of tangentially set blades, the spaces or passages between the blades opening to the atmosphere at the outer side and to a central space at the,v inner side, and means for supplying gas tovl said central space, and a movable cover device telescoping over one end of the cylinder; substantially as described.v

2. In a gas burner, a mixer comprising acylinder composed of end rings and a plurality of separated tangentiaily set-blades,

the spaces or passagesv between the blades opening to the atmosphere at the outer side and to ak central space at the inner side, a valve casing secured to one of the end rings and having connection with a source ef gas supply and also having a port comnnuncatv ing with the central'space of the mixer, a valve controlling said.` port, and a burner nozzle connected to the opposite end of the mixer; substantially as described.

3. In a gas burner, a mixer comprising a cylinder composed of end rings and a plurality of separated tangentially set-blades, the spaces or passages between the blades opening to the atmosphere at the outer side ift).

and to a centl-ral space at the inner side, a yalve casing secured to one of the lend rings and havin connection with a source of gas vsupply an also having a port communicating with the cent-ral space of the mixer, a

,. valve controlling' said' port, and a burner lnozzle connected to the opposite end of the mixer, together with means forelosing in ,any desired portion of the mixer cylinder to regulate the amount of air entering the 10 spaces or passages; substantially as described.

In testimony whereof, I have hereunto set my hand. A
